· Coolant
temperature lower than - 37 °C / - 35 °F (short
circuit to battery voltage or circuit interruption)
· Above
condition must be fulfilled for at least 1.0 s
Replacement values:
· With
ignition On and trouble codes 69 and 71 not present, the intake air
temperature is taken as the starting value.
· With
ignition ON and trouble code 69 or 71 present, 10 °C / 50 °F
is taken as the starting value.
· If
a plausible measured value has already been produced for the coolant
temperature, it is used as the starting value
· The
starting value is increased by 1 °C / 1.8 °F every
146 cycles (1 cycle = 720 °CA) to a maximum value of
99 °C / 211 °F.
This value is used for the
remaining engine operation.
Effects:
· All
adaptation except knock control, throttle valve control and idle speed
adjuster control is blocked
· The
tank vent valve is blocked and the tank vent valve closed
